anyway, during our conversation (I know the garage fairly well (Formula One - Maidstone)) I was told that there is an engine ecu and also an internal ecu . The internal one looks after all of the internal electrics, and does things like only let you open the window a little at a time rather than all at one go if your battery is low on power.

Can anyone confirm that this is true, and if so, is their any way to reset the internal ECU, since changing the battery for a brand new one the front windows still only open a little at a time, but the car starts each and everytime now, so assume the internal ECU (If its real) needs reset?
As mentioned in the other replys here the internal ECU is actually known as the UCH .
It's actually more complicated than that; there are micro processors all over the car; in the windows; the sun roof; the dash; the climate control; the auto seat position (if you have it); in the ESP/ABS; etc.

When the battery was disconnected the window controllers lost their anti-pinch settings. The procedure to reset these is described in the Forums.

It's also worth reseting the anti-pinch on the sun roof. Although you'll find the roof still seems to work the anti-pinch may not. Agin do a search of the Forums for instructions.
